Improved edging-machine



PATENT L. FAY, OF CINCINNATI, OHIO.

IIVIPROVED EDGING-lVIACHINE.

Specification forming part of Letters Patent No. 33,l90, (latedSeptember 3, 18M.

. To @ZZ whom it may concern:

Be it known that I, LUOIAN FAY, of Cincinnati, Hamilton county, Ohio,have invented a new and useful Edgiug-Machine for Sheet Metal Roofing;and I do hereby declare the following to be a full, clear, and exactdescription thereof, reference being had to the annexed drawings, makingpart of this speciiieation.

My invention relates to an automatic provision for bending or setting upthe edges of sheet metal for roofing after the single sheets havebeenunited into long si rips or courses,7 and preparatory to the iinaloperation of uniting the several courses together, theinventiou beingone of a series made by me for the more perfect and expeditious puttingtogether of sheet-metal roo-fs.

Figure l is a perspective view of a machine embodying my improvements.Fig. 2 is an axial section of a pair of finishing-rolt ers. Fig. 3 is afront elevation of the machine. v

A A A are several axles, of which each is in two separate pieces, which,by means of slots c and bolts c', can be adjusted to any width of metal.These axles are held to their proper relative positions by means of barsB, so as with said bars to constitute a frame or bed, which is supportedby a double set of wheels or rollers, C C G, of slightlyconicalperipheries, and styled the traveling7 rollers. The axles A A A projectsomewhat beyond the traveling rollers, in order to afford attachment bymeans of setscrews cl for a series of nearly perpendicular axles, D, ofrollers E E E, of which the rollers E and E have respectively the formsof an obtusely and acutely conic frustum.

Secured to the front axle, A, by set-screws fare two notched jaws, F,which, being secured to their properposition out or in upon the axle,serve to guide the machine along the course or strip z, and act as gagesfor the formation of the respective high and low iianges, y and y,required for the subsequent and final operation of double-seaming.

The machine is both propelled and is held down firmly to its work bymeans of ahandle, G, attached to its rear portion.

Operation: rIhe two series of setting-up and traveling rollers and thegages being set at the required distance apart for the particular widthof metal and for the required wide and narrow flanges, the edges of thetin,

z, must be introduced into the notches of the gages, and the machinebeing then pushed forward along the course or strip in the direction ofthe arrow, the work is done. O11 steep roofs the operator, being seatedupon the machine, may allow it to descend by gravitation, and foradditional safety the machine may be prevented from passing over theeaves by a rope attached to its rear portion.

Bractical tests upon the roof with this machine show that a singleoperator of comparatively slight skill and physical ability will set upboth edges more perfectly and in less time than four skilled workmen canset up a single edge with the customary appliances. The machine,therefore, does the work of seven men, and with greater exactness anduniformity than have been heretofore possible.

As an auxiliary and intermediate tool loetween my cross and doubleseamin g machines, the present improvement is invaluable, the flangesbeing set up absolutely vertical and to a definite and uniformrectilineal line, height, and distance apart, such perfection being moreessential for joints which are to be nished by my doubleseaming machinethan for4 the common hand operation, in which irregularities in thesetting up can be humored77 by elevating, depressing, 85o., the tool.

I claim as new and of my invention- 1. The double series of travelingand seb ting-up rollers O C C, E E E, O C O, E E E, for the simultaneoussetting up of two opposite edges ot' a metallic plate, in the mannersubstantially as set forth.

2. The described combination of traveling and setting-up rollers C andE, C and E', &c., the axle D of the setting-up roller being secured andadjusted upon the axle A A',
